M103 chapter labs

so I should change the path in my .conf to “~/var/mongodb/db/”?

  1. I would recommend to use full path name.
  2. Some validation scripts for the labs expect thing to be at the exact location requested. So if they want you to put stuff in /var/… use /var/…, nothing else.

does this seem alright to you?27%20AM

Hi Akbar_91991,

The configuration file seems right. You are doing great! Just one step, create a directory /var/mongodb/db and not var/mongodb/.

   vagrant@m103:~$ sudo mkdir -p /var/mongodb/db
   vagrant@m103:~$ sudo chown vagrant:vagrant /var/mongodb/db

And you can always use pwd command to see the working directory like:

  vagrant@m103:~$ cd /var/mongodb/db
  vagrant@m103:/var/mongodb/db$ pwd

Let me know if it helps.


any one have this error vagrant@vagrant-ubuntu-trusty-64:/data$ mongod --port 27000 --dbpath /home/data/lab1 --logpath /home/data/lab1.log --bind_ip “,” --auth --fork
about to fork child process, waiting until server is ready for connections.

To see additional information in this output, start without the “–fork” option.

The first thing to do would be to start without the –fork option like the error message suggest. Alternatively you could look at the log file to have additional information.

here is the log

so when i use the localhost only it work fine

Try removing the space between the 2 IP addresses and the comma.

mongod --dbpath /home/data/lab1 --logpath /home/data/lab1.log --port 27000 --bind_ip “localhost,” --auth --fork

still the same output

You may have another process listening to this port.

Run netstat -tlnp, to see listening sockets.
